UE5 Packing fail

[fredguy]

DOn Works in PIE, but compiling fails with :

The BTT task uses the "don navigation managor" => "find random point around origin in nav world" with target, nav actor, origon and distance connected.
However, during packaging, somehow, the pin are being discarded within the behavior tree task during compile.
